SECTION: 01 57 19 TEMPORARY ENVIRONMENTAL CONTROLS superseding 01 57 23 TEMPORARY STORM WATER POLLUTION CONTROL
Criteria
- UFGS SECTION 01 57 19 TEMPORARY ENVIRONMENTAL CONTROLS
- JBLM Municipal Separate Storm Sewer System (MS4) Permit WAS-026638
- NPDES Construction General Permit (CGP) For Storm Water Discharges From Construction Activities
- See also CGP part 9.10.3 for WA State Requirements including part S.4. (discharge monitoring) in accordance with the WA State Construction Stormwater General Permit
- EPA Inspection and Monitoring Guide for Construction Dewatering
- UFC 1-200-02 (High Performance and Sustainable Buildings Requirements)
- Army Sustainable Design and Development Policy Memo (Jan 17 2017)
Design Requirements
- All SWPPPs must be provided to the Environmental Stormwater Program for review prior to construction work. Send all submitalls requesting environmental compliance input to the ED Review email. Typical review period is two weeks.
- EPA CGP Stormwater Pollution Prevention Plan (SWPPP) Template for project disturbing 1 acre or more.
- Copy of EPA eNOI must be submitted to the Stormwater Program prior to construction.
- Draft of EPA NOT with photos demonstrating stabilzation requirements have been met must be submitted to the Stormwater Program for review prior to EPA submittal.
- JBLM SWPPP Template for MS4 permit construction compliance for projects disturbing 5,000 sq.ft. or more.
- Use the Stormwater Management Manual for Western Washington for TESC BMP selection, design, implementation, and maintenance guidance.
- Erosion and Sediment Control: Provide appropriate erosion and sediment controls on all construction sites that will have ground disturbance. For sites with 5,000 square feet or less of ground disturbance may include a description of erosion and sediment controls and site map in the Environmental Protection Plan (See Section 01 57 20.00 10). Proper implementation and maintenance of appropriate best management practices (BMPs) is critical to adequately control any adverse water quality impacts from construction activities. Discharges must not violate the state's surface water quality standards (WAC Chapter 173-201A) and groundwater quality standards (WAC Chapter 173-200).
- Volume II, Chapter 4 of the Ecology stormwater manual provides standards and specifications for BMPs that are approved for use on JBLM. Consider other BMPs with proper review and approval by JBLM PW.
- Preparation of a site-specific SWPPP is required for all construction activities that will have a land disturbance of 5,000 square feet or more or are part of a common plan of development that will disturb 5,000 square feet or greater. Multiple construction sites under one contract must have a SWPPP prepared if the total land disturbance for all sites is greater than 5,000 square feet.
- Construction sites that will have a land disturbance of one or more acres (or are part of a common plan of development that will disturb an acre or greater) or projects that have multiple construction sites under one contract if the total land disturbance for all sites is greater than one acre, must be covered under the EPA's NPDES CGP (Construction General Permit).
- Construction Discharge Monitoring: WA State specific guidance under part 9 of the CGP requires monitoring of any discharge leaving the construction site for turbidity and for pH during concrete work.
- Sampling is required weekly at all points where construction stormwater is discharged off site, including where it enters any surface waters of the state. Sample ponts must be identified in the SWPPP site map and in the field with flag, tape, stake, or other visible marker.
- Turbidity monitoring can be completed with a calibrated turbidity meter (logged in NTUs) with aor transparency tube (logged in centimeters).
- Turbidity benchmark: 25 NTU
- Transparency benchmark: 33 cm
- Turbidity 26 – 249 NTUs, or Transparency 32 – 7 cm:
- Immediately begin the process to fully implement and maintain appropriate source control and/or treatment BMPs.
- Notify the Stormwater Program and update SWPPP within 7 days.
- Turbidity 250 NTUs or greater, or Transparency 6 cm or less
- Immediately begin the process to fully implement and maintain appropriate source control and/or treatment BMPs as soon as possible, addressing the problems within 10 days of the date the discharge exceeded the benchmark.
- Immediately notify the Stormwater Program Manager (253) 967-2837, provide Corrective Action Log within 24 hrs., and update SWPPP within 7 Days.
- Sample discharges daily until discharge is below benchmarks or discharge stops or is eliminated.
- When concrete work is being performed weekly pH analysis must be completed on site with a calibrated pH meter, pH test kit, or wide range pH indicator paper. Record pH sampling results in the inspection log maintained with the SWPPP.
- Anytime sampling indicates that pH is 8.5 or greater corrective actions must be taken to adjust or neutralize the pH and/or eliminate the discharge.
- Dewatering activities must inspected using the EPA Dewatering Inspection Report Template and monitored for turbidity or managed on site with appropriate BMPs.
- Permit Noncompliance, Illicit Discharges, and Spills:
- An EPA Corrective Action Log within 24 hrs to be maintained with the SWPPP and sent to the ED Stormwater Program for review.
- SWPPP modifications must be completed within 7 days and sent to the ED Stormwater Program for review.
- Spill reporting must follow standard JBLM processes to call 911. Any discharges or spills to a body of water must also immediately inform the Stormwater Program Manager at (253) 967-2837.
Notes to Designers on Drawing Content
- Required Construction BMPs:
- C103 High Visibility Fence - Around new stormwater facilities, trees to be retained, and any disturbed areas where foot or vehicle traffic may occur prior to final stabilization of the area.
- C120 Temporary and Permanent Seeding - Used on topsoil stockpiles and throughout the project on distubred areas that have reached final grade or will remain unworked for 30 days or more.
- C122 Nets and Blankets for slopes 2H:1V or greater. Use 100 percent biodegradable blankets for sensitive areas including creek banks.
- C220 Inlet Protection - inlet filters are generally insufficient to protect the storm system. Incorporate wattles, sand bags, or rock bags as appropriate for the site.
- Both TESC BMPs (e.g., wattles and temporary sediment ponds) and permanent facility BMPs (e.g., bioretention swale) must be included in SWPPP drawings and maps. Select BMP information and figures from the SWMMWW.
- BMP T5.13 Post Construction Soil Quality and Depth is required for all lawn and landscaped areas. Top soil must be 8" with organic content exceeding 5% and pH between 6.0-8.0.
